i have compared i had the first results with the last tetra strip and they were I agree. So far I have duplicated the tests and compared the strips and the results have been the same. After reading many reviews about the inaccuracy of these tests, but after positive responses to my question regarding the purchase, I wanted to be cautious. So: So far I can say that my test series delivers accurate results. However, the test pads tend to smear a bit on the strip they are on, but not among themselves. All I have to do to avoid this is quickly dip them in the water and then pat them very firmly on the sides to remove the excess water. I love all the information out there about water quality as it is good for your life too. Plant.
